A smile can hide the pain one is feeling inside but doesn’t need to be shown to others. A smile can show happiness. A smile can also be a mask used to hide & trick people to think you are happy when really underneath that smile is a sad, worried , angry, depressed face that wants to be happy but just can’t find the strength to show how he/she feels because they don’t want others to feel sorry or they don’t want others to worry about them thinking that the person is going to do something that will change their loved ones lives.
